| /* Notes: |
| * Before you start changing something in this file be aware of the following: |
| * |
| * - There are several functions called recursively. In a very subtle and |
| * obscure way. DLLs can reference each other recursively etc. |
| * - If you want to enhance, speed up or clean up something in here, think |
| * twice WHY it is implemented in that strange way. There is usually a reason. |
| * Though sometimes it might just be lazyness ;) |
| * - In PE_MapImage, right before fixup_imports() all external and internal |
| * state MUST be correct since this function can be called with the SAME image |
| * AGAIN. (Thats recursion for you.) That means MODREF.module and |
| * NE_MODULE.module32. |
| * - No, you (usually) cannot use Linux mmap() to mmap() the images directly. |
| * |
| * The problem is, that there is not direct 1:1 mapping from a diskimage and |
| * a memoryimage. The headers at the start are mapped linear, but the sections |
| * are not. For x86 the sections are 512 byte aligned in file and 4096 byte |
| * aligned in memory. Linux likes them 4096 byte aligned in memory (due to |
| * x86 pagesize, this cannot be fixed without a rather large kernel rewrite) |
| * and 'blocksize' file-aligned (offsets). Since we have 512/1024/2048 (CDROM) |
| * and other byte blocksizes, we can't do this. However, this could be less |
| * difficult to support... (See mm/filemap.c). |
| * - All those function map things into a new addresspace. From the wrong |
| * process and the wrong thread. So calling other API functions will mess |
| * things up badly sometimes. |
